Background: In Europe, ofatumumab is approved for breastfeeding, but data on its transfer into breast milk and clinical experience are lacking.
Objective: To analyze (1) health, development, and adverse events after live vaccination of ofatumumab-exposed breastfed infants and (2) detectability of ofatumumab in breast milk, and to calculate the relative infant dose (RID) using two methods, the traditional method and a second method considering maternal exposure to multiple ofatumumab doses and extended collection period.
Methods: In this observational study, clinical data were collected by standardized telephone interviews up to 2 years postpartum.
Background: Information on symptomatic therapy (ST) use in women of childbearing age with multiple sclerosis is sparse, and data on the impact of ST pregnancy exposure on pregnancy outcome are lacking.
Objective: To investigate (1) ST use patterns pre-conception, during pregnancy and postpartum and (2) pregnancy outcomes.
Methods: Pregnancy data from the German Multiple Sclerosis and Pregnancy Registry were analyzed for the ST use from pre-conception to postpartum.
